National Instruments Wireless Sensor Network Platform
The NI Wireless Sensor Network (WSN) platform simplifies remote monitoring applications and delivers a complete, customizable monitoring solution. NI WSN hardware reduces installation and maintenance costs while delivering a flexible solution that features industrial ratings and extremely low power consumption. Because of their low power consumption, NI WSN measurement nodes are ideal for energy harvesting applications. With operational power on the order of 300mW, WSN end nodes can operate for up to 3 years on their internal 4 AA batteries, or indefinitely with the use of energy harvesting devices.

In addition, LabVIEW integration with NI Wireless Sensor Networks simplifies the extraction of high quality measurement data. LabVIEW graphical programming delivers advanced data analysis and visualization, including web-based data access and node programming for local processing, analysis, and control using the LabVIEW WSN Module.
LabVIEW Drivers for Third Party WSN Products
LabVIEW provides a wide range of connectivity options through open protocols, instrument drivers, and a development environment that you can use to build your own connectivity. To simplify connectivity to third party WSN devices, engineers at National Instruments have developed LabVIEW drivers for wireless sensor networks from Accsense, Accutech, Banner Engineering, and Crossbow Technology gateways. You can also use OPC or Modbus to connect to other wireless gateways including Sensicast devices.

Integrating Wired and Wireless Data
Using LabVIEW, you can integrate existing wired measurements with new wireless data from a variety of vendors. For enterprise connectivity, LabVIEW supports open protocols such as Wi-Fi and new industrial Wi-Fi devices such as the NI WAP-3701 wireless access point. The NI platform helps you customize and enhance your WSN architecture even further. With LabVIEW integration and the flexibility of Ethernet connectivity, you can add other devices and functionality to your WSN system. This can range from Enterprise-level devices such as databases and servers to wired I/O, control systems, or 3rd party WSN products. LabVIEW Real-Time enables embedded data logging and open communication on the gateway, while LabVIEW WSN enables node customization and local decision making at the node level.

In addition to customizable hardware connectivity, LabVIEW integration can enhance the capabilities of your wireless measurement system. Besides the advanced processing and visualization capabilities that are common in LabVIEW, you can use native enterprise-level connectivity features to integrate your system with a database to house your data or perform intensive analysis that might not be suited for your host controller. Furthermore, LabVIEW Web services give you the opportunity to publish your measurement data to a Web server, such as the integrated Web server on the NI 9792, delivering convenient remote access to your WSN from virtually anywhere. These software enhancements provide connectivity from the enterprise level all the way to end clients. With this complete system architecture, you can quickly and easily acquire data from virtually anywhere using a wireless sensor network, process and host that data on a server, and then access the data conveniently and remotely from a wireless smart device, such as an iPhone or laptop.
